In a carburetor attachable to an air cleaner wherein the carburetor has an air passage with a choke valve therein pivotable from a closed position to a full open position, the improvement comprising: a stud mounted on the carburetor upstream of the choke valve for attaching the air cleaner to the carburetor; and a finger element mounted on said stud and projecting into contact with the choke valve to hold the choke valve in a slightly open position whereby the finger element prevents the choke valve from closing.
Claim 3
Dependent Claim
42 words
An improvement as defined in claim 1 wherein said finger element is readily manually bendable generally toward and away from the pivotal axis of the choke valve to permit adjustment of the opening of the choke valve in the slightly open position.
Claim 4
Dependent Claim
